SAFETY FEATURES
ANTI-LOCK BRAKE SYSTEM (ABS)
The Anti-Lock Brake System (ABS) provides increased vehicle stability and brake performance under most braking conditions. The system automatically prevents wheel lock, and enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure that the ABS is working properly each time the vehicle is started and driven. During this
self-check, you may hear a slight clicking sound as well as some related motor noises.
ABS is activated during braking when the system detects one or more wheels begin to lock. Road conditions such as ice, snow, gravel, bumps, railroad tracks, loose debris, or panic stops may increase the likelihood of ABS activation(s).
You also may experience the following when ABS activates:
These are all normal characteristics of ABS.
ABS is designed to function with the Original Equipment Manufacturer (OEM) tires.
Modification may result in degraded ABS performance.
The yellow“Anti-Lock Brake Warning Light” will turn on when the ignition is placed in the ON/ RUN mode and may stay on for as long as four seconds.
If the“Anti-Lock Brake Warning Light” remains on or comes on while driving, it indicates that the anti-lock portion of the brake system is not functioning and that service is required.
However, the conventional brake system will continue to operate normally if the“Anti-Lock Brake Warning Light” is on.
If the“Anti-Lock Brake Warning Light” is on, the brake system should be serviced as soon as possible to restore the benefits of anti-lock brakes. If the“Anti-Lock Brake Warning Light” does not come on when the ignition is placed in the ON/RUN mode, have the light repaired as soon as possible.
ELECTRONIC BRAKE CONTROL (EBC) SYSTEM
Your vehicle is equipped with an advanced Electronic Brake Control (EBC) system. This system includes Electronic Brake Force Distribution (EBD), Anti-Lock Brake System (ABS), Brake Assist System (BAS), Hill Start Assist (HSA), Traction Control System (TCS), Electronic Stability Control (ESC), and Electronic Roll Mitigation (ERM). These systems work together to enhance both vehicle stability and control in various driving conditions.
Your vehicle may also be equipped with Ready Alert Braking (RAB), and Rain Brake Support (RBS).
The Brake Assist System (BAS) is designed to optimize the vehicle’s braking capability during emergency braking maneuvers. The system detects an emergency braking situation by sensing the rate and amount of brake application and then applies optimum pressure to the brakes. This can help reduce braking distances. The BAS complements the Anti-Lock Brake System (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the benefit of the system, you must apply continuous braking pressure during the stopping sequence (do not“pump” the brakes). Do not reduce brake pedal pressure unless braking is no longer desired. Once the brake pedal is released, the BAS is deactivated.
The red“Brake System Warning Light” will turn on when the ignition is placed in the ON/RUN mode and may stay on for as long as four seconds.
If the“Brake System Warning Light” remains on or comes on while driving, it indicates that the brake system is not functioning properly and that immediate service is required. If the“Brake System Warning Light” does not come on when the ignition is placed in the ON/RUN mode, have the light repaired as soon as possible.
Electronic Brake Force Distribution (EBD) This function manages the distribution of the braking torque between the front and rear axles
by limiting braking pressure to the rear axle.
This is done to prevent overslip of the rear wheels to avoid vehicle instability, and to prevent the rear axle from entering ABS before the front axle.
Electronic Roll Mitigation (ERM) anticipates the potential for wheel lift by monitoring the driver’s steering wheel input and the speed of the vehicle. When ERM determines that the rate of change of the steering wheel angle and vehicle’s
speed are sufficient to potentially cause wheel lift, it then applies the appropriate brake and may also reduce engine power to lessen the chance that wheel lift will occur. ERM can only reduce the chance of wheel lift occurring during severe or evasive driving maneuvers; it cannot prevent wheel lift due to other factors, such as road conditions, leaving the roadway, or striking objects or other vehicles.
ERM is disabled anytime the ESC is in“Full Off” mode (if equipped). Refer to“Electronic Stability Control (ESC)” in this section for a complete explanation of the available ESC modes.
The Electronic Stability Control (ESC) system enhances directional control and stability of the vehicle under various driving conditions. ESC corrects for oversteering or understeering of the vehicle by applying the brake of the appropriate wheel(s) to assist in counteracting the oversteer or understeer condition. Engine power may also be reduced to help the vehicle maintain the desired path.
ESC uses sensors in the vehicle to determine the vehicle path intended by the driver and compares it to the actual path of the vehicle. When the actual path does not match the intended path, ESC applies the brake of the appropriate wheel to assist in counteracting the oversteer or understeer condition.
The“ESC Activation/Malfunction Indicator Light” located in the instrument cluster will start to flash as soon as the ESC system becomes active. The“ESC Activation/Malfunction Indicator Light” also flashes when the TCS is active. If the“ESC Activation/Malfunction Indicator Light” begins to flash during acceleration, ease up on the accelerator and apply as little throttle as possible. Be sure to adapt your speed and driving to the prevailing road conditions.
Depending upon model and mode of operation, the ESC system may have multiple operating modes.
This is the normal operating mode for the ESC. Whenever the vehicle is started, the ESC system will be in this mode. This mode should be used
for most driving conditions. Alternate ESC modes should only be used for specific reasons as noted in the following paragraphs.
The“Partial Off” mode is intended for times when a more spirited driving experience is desired. This mode may modify TCS and ESC thresholds for activation, which allows for more wheel spin than normally allowed. This mode may be useful if the vehicle becomes stuck.
To enter the“Partial Off” mode, momentarily push the“ESC OFF” switch and the“ESC OFF Indicator Light” will illuminate. To turn the ESC on again, momentarily push the“ESC OFF” switch and the“ESC OFF Indicator Light” will turn off.

"Traction Sport" and "Traction Track" (if equipped) are ESC“Partial Off” mode(s). Upon the first push of the ESC button the system goes into SPORT mode, indication comes on in the cluster (a picture of the vehicle with the word SPORT), and the light in the cluster is illuminated. The second push of the ESC button the system will go into TRACK mode, indication comes on in the cluster (a picture of the vehicle with the word TRACK),
and the light in the cluster remains illuminated. When it is pushed a third time the ESC will go back into“ESC On”, no indication, and the illumination in the cluster turns off.
This mode is intended for off-highway or
off-road use only and should not be used on any public roadways. In this mode, TCS and ESC features are turned off. To enter the“Full Off” mode, push and hold the“ESC OFF” switch for five seconds while the vehicle is stopped with the engine running. After five seconds, a chime will sound, the“ESC OFF Indicator Light” will illuminate, and the“ESC OFF” message will display in the instrument cluster. To turn ESC on again, momentarily push the“ESC OFF” switch.
The“ESC Activation/Malfunction Indicator Light” in the instrument cluster will come on when the ignition is placed in the ON/RUN mode. It
should go out with the engine running. If the“ESC Activation/Malfunction Indicator Light” comes on continuously with the engine running, a malfunction has been detected in the ESC system. If this light remains on after several ignition cycles, and the vehicle has been driven several miles (kilometers) at speeds greater than 30 mph (48 km/h), see an authorized dealer as soon as possible to have the problem diagnosed and corrected.
The“ESC Activation/Malfunction Indicator Light” (located in the instrument cluster) starts to flash as soon as the tires lose traction and the ESC system becomes active. The“ESC Activation/Malfunction Indicator Light” also flashes when TCS is active. If the“ESC Activation/Malfunction Indicator Light” begins to flash during acceleration, ease up on the accelerator and apply as little throttle as possible. Be sure to adapt your speed and driving to the prevailing road conditions.
The“ESC OFF Indicator Light” indicates the customer has elected to have the Electronic Stability Control (ESC) in a reduced mode.
The Hill Start Assist (HSA) system is designed to mitigate roll back from a complete stop while on an incline. If the driver releases the brake while stopped on an incline, HSA will continue to hold the brake pressure for a short period. If the
driver does not apply the throttle before this time expires, the system will release brake pressure and the vehicle will roll down the hill as normal.
The following conditions must be met in order for HSA to activate:
HSA will also provide assistance to mitigate roll back while towing a trailer.
This feature can be turned on or turned off. To change the current setting, proceed as follows:
For vehicles not equipped with an instrument cluster display, perform the following steps:
Rain Brake Support (RBS) may improve braking performance in wet conditions. It will periodically apply a small amount of brake pressure to remove any water buildup on the front brake rotors. It functions when the windshield wipers are in LO or HI speed. When Rain Brake Support is active, there is no notification to the driver and no driver interaction is required.
Ready Alert Braking (RAB) may reduce the time required to reach full braking during emergency braking situations. It anticipates when an emergency braking situation may occur by monitoring how fast the throttle is released by the driver. The Electronic Brake Controller (EBC) will prepare the brake system for a panic stop.
The Traction Control System (TCS) monitors the amount of wheel spin of each of the driven wheels. If wheel spin is detected, the TCS may apply brake pressure to the spinning wheel(s) and/or reduce engine power to provide enhanced acceleration and stability. A feature of the TCS, Brake Limited Differential (BLD), functions similarly to a limited slip differential and controls the wheel spin across a driven axle. If one wheel on a driven axle is spinning faster than the other, the system will apply the brake of the spinning wheel. This will allow more engine power to be applied to the wheel that is not spinning. BLD may remain enabled even if TCS and ESC are in reduced modes.
